Be i t known that I, GEORGE Wnnsrmn COUL- TAS, of Calais, in the county of Monroe and State of Ohio, have invented a new and Improved Bridge, of which the following isa full, clear, and exact description.

The object of my invention is to provide a new and improved bridge which is simple and durable-in construction and specially adapted for shortspan country bridges.

The invention consists in the construction and arrangement of various parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Iteference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure-l is a side elevation of my improvement, with parts in section; and Fig. 2 is a vertical cross section of the same on the lines 00 x of Fig. 1.

The abutment cross-beams A A support the longitudinal single-span beams B, on which are fastened the planks O, in the usual manner.

In the middle of the span-beams B, on the under side, is placed the cross-beam D, clipped on each side by the clip E to a bolt, F, passing transversely through the lower end of the upright beam G, resting on the said crossbeam D, and connected at its upper end with the top rail, H, supported at each end by the end uprights, I I, secured to and resting on the abutmerit-beams A A. Each bolt F passes through a recess, G, in the beam G, and on each bolt F is pivotally held one end of the four diagonal braces J, which extend upward in pairs in opposite directions to each other and pass through the ends of the top rails, H, and are held in pl ace by the plates and nuts K, screwing against the ends of the said top rails, H.
